Cloud Computing has allowed businesses and individuals to access powerful computational resources from anywhere in the world. This has allowed companies to put more focus on aspects that matter without having to worry about the hardware aspect of Software Development and Deployment. There are a variety of services and models in Cloud Computing, each with varying levels of abstraction and control. This blog aims to guide and explore the different cloud computing services and models so that you can choose the right one for your business needs.

What is Cloud Computing?
In the computer science domain, the term “Cloud Computing” refers to the delivery of computing resources like servers, storage, databases and networking over the internet. Instead of buying and maintaining expensive hardware, individuals and business organizations can use cloud services provided by third-party companies. They use various services offered by cloud computing providers such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
Cloud Computing has allowed businesses to quickly and easily provision computing resources on a demand basis.
Additionally, because cloud computing providers manage and maintain the underlying infrastructure, businesses can focus on developing and deploying their applications and services.

What are Cloud Models?
It refers to the practice of accessing and utilizing computing services over the internet, fundamentally transforming the world of IT.
Depending on the provider and the user requirement the cloud model is divided into two bases:
- Types of Cloud Computing Based on Service Model
- Types of Cloud Computing Based on Deployment Model

Types of Cloud Computing Based on Service Model
Cloud Computing services can be divided into three main types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each of these services offers a different level of abstraction and control over the computing resources used.
By going through these types: IaaS, PaaS, and SaaS, users can choose the kinds of service that best fits their organization’s requirements.
1. Infrastructure as a Service
Infrastructure as a Service refers to the Cloud Computing solution allowing users to access computing resources over the internet in a quick and flexible manner. Customers attain greater power and agility over their computing resources by controlling their operating systems, applications, and storage.
More specifically, they can scale up or down to a desired number. All these are provided without the hassle of managing the underlying physical infrastructure, which the IaaS provider handles, including servers, storage, and networking tools. This service is ideal for companies aspiring for maximum control and efficiency over their information resources.
Platform as a Service refers to the Cloud Computing solution that provides users with a platform for creating and releasing applications. This allows users to release applications without having to worry about the underlying infrastructure.
By outsourcing the requirement of equipment, software, and servers to the service provider, PaaS enables developers to quickly collaborate with team members, build and try out applications, and release them to the cloud with ease. Through PaaS, businesses can reap several benefits, such as lower infrastructure costs, faster development, and improved agility.
3. Software as a Service
Software as a Service (SaaS) is a cloud computing model that provides users with software applications over the Internet.
With this model, SaaS providers host and manage the software and infrastructure on their own, eliminating the need for users to install and maintain software on their own devices. Thus, making it an attractive, as well as cost-effective solution for businesses and individuals.
Moreover, users can access SaaS software anytime with a convenient, easy-to-use web browser or application interface. It is an all-encompassing solution with a subscription fee for service, updates, and support. Some examples of SaaS include Gmail for Email services and Salesforce for Customer Relationship Management (CRM).

Types of Cloud Computing Based on Deployment Model
The three primary cloud computing deployment models are public, private, and hybrid.
- Public Cloud- A cloud computing service is a model operated by a third-party provider, offering users various computing resources such as servers, storage, and applications. The resource can be accessible over the Internet on a pay-per-use basis.
AWS, Microsoft Azure, and Google Cloud Platform are some of the providers of public cloud services. Users can tap into the resources by utilizing complexity and sentence variation, unlocking their full potential.
- Private Cloud- A private cloud gives the organization or teams minute control over all the aspects of the resources and services allowing higher customization and security over a public cloud. It can be on-premises or off-premises, which are tailored to fit the specific demands of an organization, no matter its size or need.
Organizations, government departments, and various other entities can take complete advantage of the outstanding control, optimization, and data accessibility that a private cloud provides. With this in mind, private clouds offer a unique opportunity to store data safely and securely. while providing a cost-effective, convenient, and highly customizable cloud solution.
- Hybrid Cloud- Combining the robust security of a private cloud with the agility and scalability of a public cloud, hybrid cloud computing offers organizations the best of both.
With the comprehensive protection of on-premises servers and the flexibility of public clouds, hybrid cloud computing allows organizations to run applications and workloads requiring additional security, compliance, and performance levels. This hybrid approach will enable businesses to keep sensitive data and applications on-premises while reaping the benefits of the public cloud.
Benefits of Cloud Computing Services
Cloud computing services offer numerous advantages to both businesses and individuals. Here are some of the key benefits of cloud computing services:
- Cost Savings- Cloud computing allows businesses to save time and money by avoiding the need for expensive hardware, software, and infrastructure. Furthermore, cloud providers offer subscription-based pricing, making it easy for businesses to pay for only what they need.
- Scalability- Cloud computing services are highly adjustable, which signifies businesses can expand or shrink their computing resources depending on their requirements. It is incredibly convenient when companies need to accommodate unpredicted spikes in traffic or sudden increases in demand.
- Flexibility- Cloud Computing allows users and organizations to access resources and services over the internet. It is particularly beneficial for mobile teams and those who work remotely.
- Reliability- Opting for the cloud allows businesses always to access the data and applications they need; cloud providers guarantee high uptime and reliability. With these services and resources, we can also enable disaster recovery and backup services allowing quick recovery from any potential outages.
- Security- Businesses can rest assured knowing their data is secure with cloud computing. Cloud providers usually have higher and more advanced security in the form of encryption, firewalls, and access management to protect data from any potential cyber-attacks or breaches.
